JOI-IN A. TUPPER, OF MONTPELIER, IDAHO.

IEIILEIC'ILBIC` RADIATOR.

Be it known that I, JOHN A. TUPPER, a

`citizen of the United States, residing at Montpelier, in the county of Bear Lake and State of Idaho, have invented certain newA and useful Improvements in Electric Radiators, of which the following is a specification, reference being had therein to the ac-y companying drawing.

This invention. relates to electric heaters in which a plurality of resistance coils are placed in the circuit of an electric current and are adapted to heat the liquid contained i within the heater.

The object of this invention is to provide an improved electric heater bv means of which the heatmay be regulated.

With these and other objects in view this invention consists of certain novel constructions, combinations and arrangements of parts as will be hereinafter fully described and claimed.

In the drawings: Figure 1 is a. longitudinal section of the heater showing the coils positioned therein gFig. 2 is an end view of the heater.

Referring to the drawings by numerals,

v1 designates the casing of the heater, which comprises a plurality of hollow sections or chambers 2. These sections are connected in the ordinary `manner and to one of the outer sections is secured an inlet pipe 3, through which can be poured the oil or liquid to be contained within the heater 1. Upon the opposite end of the heater or outer section is secured a pair of knobs or caps 4, which normallyl close the o enings 5,

which openings facilitate the placing of the cores or coils within the heater and also allow the liquid .to be drained from the heater when it is so desired.

Adapted to be positioned within the lieat-er and extend longitudinally vof the 45jsame and through the nipples or ordinary connecting means, 6, are cores or longitudinally-extendin 'members 7. It is desirous of having two o these cores, at least, within the heater, one in the upper portion thereof and one in the lower portion. Around each core 7 is positioned a resistance coil 8. Positioned contiguous to the heater 1 is a circuit,4 closure or switch 9 and said switch is electrically connected to a lamp socket 10 to which extend feed ,wires 16 one of which is continued as at 18 to the lower resistance coil. The switch'is, preferably, a two-way i Specification of Letters llatent. Patented NOV, 22, 1910,

switch, which when forming a contact with one terminal 11 will causethe current to only iow around through the lower resistance coil 8l The terminal v11 is electrically connected to the lower resistance coil S by means ot a. conductor 13. T he other terminal l5 of the two-way switch is electrically connected to the upper coil 8, by means of a conductor 19 and when the lever oi' switch 9 is thi-own into contact with the terminal l5, it. will cause thev currento flow through both otl the resistance coils, therefore, greatly decreasing the 'amount of heat to vbe radiated Ifoin the heater,'while, when the switch S) is on the contact 11 the'current will fiow only through the lower lcoil thus increasing the heat of said lower coil. A

It is preferable to have the heater or casing 1, contain oil which is non-conducting and which will retain the heat to a great extent. By having the coils 8 positioned upon the cores i', which are, preferably, formed oi` porcelain or some non-conductive material.

it will be obvious that the coils can be easily held in place and prevented from becoming distorted. y n

It is especially to be noted that the coils and cores do not extend into the end sections of the radiator and the cores are surrounded by annular spaces between the sections.` By

reason of this peculiar arrangement. the

outer sections are left free for the cooler oil to descend after rising to the top of the heater inthe remaining sections. Furthermore, by reason of the provision of the an nular passages between the sections, the oil is forced during its circulation in a thin film over the heating coils.

From the foregoing description, it will be readily seen that I have provided ine'ansfor regulating the heat of the radiator by throwing either one or both of the resistance coils into the circuit. Although the preferred wiring is shown in the oiiicial drawing, it should be understood that any combination of electrical connect-ion to increase or decrease tlie amount of current taken, and, consequently, the amount of heat generated could be used. l

What I claim'is: i.

In a heater of the class described, a casing provided with a series of vertical circu-V alined passages connecting the lower' ends of chambers whereby the outer chambers resaid chambers, cores extendlng through said main cooler than the lnner chambers. 10
